529 vs UTMA Tax Comparison Calculator
529 plans and UTMA accounts both let parents save for kids — but tax treatment, control, and financial aid impact differ greatly. 529: tax-free growth and qualified withdrawals for education, parent controls forever. UTMA: tax-advantaged via kiddie tax rules, but child takes ownership at 18-21 with full control over use.
529 Plan Tax Mechanics
Contributions: after-tax (federal), some states allow state-tax deduction (NY up to $10K/yr, IN $1,500 credit). Growth: tax-free. Withdrawals: tax-free for qualified education expenses (tuition, fees, books, room, board, K-12 tuition up to $10K/yr per student). Non-qualified withdrawals: earnings portion taxed as ordinary income + 10% penalty. SECURE 2.0 allows $35K lifetime rollover to Roth IRA per beneficiary.
UTMA Account Mechanics
Contributions: irrevocable gift to minor. Tax treatment via kiddie tax: unearned income up to $1,300 (2026) tax-free, next $1,300 taxed at child's rate, above $2,600 taxed at parent's rate. At age of majority (18-21 state-dependent), child takes full control — can use for any purpose. No penalty for non-education use. No FAFSA preferential treatment — counts as student asset (20% reduction in aid).
Hybrid Strategy
Many planners recommend split: 70-80% into 529 (highest tax efficiency for education) + 20-30% UTMA (flexibility for non-education uses like car, gap year, business startup). If child gets full scholarship or doesn't attend college, you can roll up to $35K of 529 to Roth IRA per beneficiary under SECURE 2.0 — solves most non-education concern.
